To all whom it may concern.

Be it known that I, JOHN F. llrlCCANNA, a citizen of' the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Lubricating Systems, of which the following is a specification. This invention relates primarily to a lubricating system, in which oil is forced through suitable connections from a plurality oi sources of supply, containing oil of different grades or kinds, to the different parts to he lubricated with the particularkinds or grades of oil contained in the sources of supply.

One of the objects of the invention is to provide a system in which the oil is delivered from a suitable rcservior or reservoirs through suitable sight feed deviccs which are mounted on a common support (aboard and compactly assembled so as to be readily inspected by the 'attcnda ie to determine the rate of feed and which'is provided with means for controlling the suppl yto any bearing or part independently of the others.- The in\."entiou also contemplates the provision of a force iced lubricating system adapted to feed oil 01' different kinds or grades to ccrtainof the parts to be lubricatcdpand providcd with a puinp common to all of the reservoirs [oi forcing oil from any one of such reservoirs to the parts to be lubricated. i

The invention has for a further obj ct to provide means for charging thesight feed glasses with water by the common pump, the organization of the parts being such that the pump may be placed in communication with a source of water supply or the source of oil suppl'y, or any one of such sources in case the system is zulapted to supply oils of different kinds or grades.

Other objects of the invention will be apparent from the aeciunpanying specification, in which the invention is fillly describcd, and the appended claims in which the novclty of the invention is set forth.

Figure l is a front. clcvation oi the invention showing the sight feed devices, pumps, and gages associated therewith, assembled ona board; Fig. 2 is a section on the. line 2-2'of Figjl; Fig. is adetail sectional view of thc auxiliary pump; Fig. 4 is a scctiouon the line 4-4 of" Fig. 1; Fig. 5 is a section on the line-5 of Fig. 2 showing the rear of the board; Fig. ti is a section on the line (i (S iii Fig. l, and Fig. 7 is a detail se tional view of one of the pumps.

The apparatus may be mounted or assembled on any suitable support. In the present inslancc [have shown the same as'assembled on a board 9 mounted on suitable legs and which with the sight feed dcviccsJvalvcsl gage glasses, etc. presents somewhat the appearance and has some of the charucterist ics of a. switchboard, the feeding of oil to any bearing being controlled and the rate or delivery of the (iil being determined at such board.

Mounted on the board are sight feed devices l0, 11, one of which is associated with each part or hearing being lubricated. Each feeding device 10,1 l, in the present embodiment of the invention, consists, as

shown in Fig. 4., of a, glass secured against leakage at its ends in the usual manner in'an upper casing 12 and' a lower valve casing 13, which casings pass through suitable apertures in the board 9, and are held in position by collars l4 and clamping nuts 15 as shown.

Connections, such as the pipes 16, are-coupled to the casings l2, and lead to the pumps 17 eachof the latter being connected by a pipe lttwith a particular sight feed glass. 1

. In the embodiment of the invention illustrated provision is made for supplying oil of different kinds or grades, the oil drawn from one source of supply passing through certain of the sight feed glasses while the oil from another of the sources of oil supply passes through other sight feed glassesf In the'present instance the system is adapted to feed two kinds or grades of oil, id

though it is to be understood that the system may be extended so that any number of kinds or grades oi oil may be supplied thereby. As shown in the drawings two reservoirs are provided, one of which, as 18, may

contain engine oil, while the other, as 19, may contain cylinder oil, assuming that the board is located in an engine 'roonnand system designed to lubricate'the v 4 engine cylinders anyl other parts. The reservon's l8 and 19 are preferably located in an elevated position as shown and are supplied with outlet pipes 20, 21 which enter headers or auxiliary reservoirs 22, 23, horizontally disposed at the back of the board 9, the header 22 being located back of the sight feed glasses 10 and the header 23 back of the sight feedjglasses'll as shown in I Figs. Zand 5. Lcadingfrom the header 22 to the valve casing 13 of each of the sight fecdglasscs 10 is a connection 2-1 Figs 2, 4, and 5, while a similar connection 25 leads from the header 23 to the valve casing 13 of each ot' the sight iced glasses ll as indicated in dotted lines in Fig. 5. As-shown in Fig. 4 each valve casing 13 is prowided with a horizontal passage 26 which is closed bya screw valve 27 the stem of which is in threaded e'ngage mentvwith a sleeve 28 projecting in front of the board and is provided with a hand wheel 29. Leading from the passage 26 is an upward duct 30 which discharges to a reducing nozzle 3]. screwing onto theeasiuglfi and having a chamber at its lower end in which is located a check valve 32 adapted to seat over and on the outlet of the duct, as shown. By means of the valve 27 with which each sight feed glass is provided, the feeding of other part to bclubri( 'atcd, there being as many pumps ..s trie are sight feed glasses. These pumps may be of any suitable or preferred character and operated in any desired manner.

In the construction illustrated the pumps are sup 5 ported by a table or ledge 33 located under the iced board and provided with a rib or flange 34 to form of the table a drip pan. Mounted in suitable bearings 35 de pending from the table and one of which is shown in dotted lines in Fig. 2, is aneccentric shaft 36 with which 1 cooperates sleeves or yokes 37 provided with links 38 pivotally connected at the upper ends to a cross head 39, extending as shown in Fig. 1, substantially the length of the table 33. This cross head is provided at its ends with slee'ves 40 adapted to slide on and be guided by vertical rods 41 on the ends of the table. At-

tached to the crosshead'39 are the pump plungers 42 the barrels 43 extending through the table, as shown in Figs. 2 and 7; and being suitably secured in position as shown. The barrel of each pump communicates .Q with a horizontal passage 44 having an inlet 45 to which I I the pipe 16 of the associated gage glass is connected, suchinlet being adapted to be closed by a suction valve 46; and the pump discharges by a passage {17 entering a chamber 48 containing a check valve {19. Ducts 50 2 conduct the oil from thechainber 48 to the tube or conn'ection 5]; leading to the part supplied with oil by such pump. Each pump plunger is provided with a pair of' abutments 52, 53 with which the cross head cooperates to reciprocate the plnngers, andone oi the abutments 30 on each plunger, as 52, is adjustable, being in the present instance in the form of a nut threaded upon the plunger. By screwing the nut up or down lost motion between the cross head and the plungonmay be varied or entirely eliminated, so as to vary the stroke ofthe 35- plunger and consequently the quantity of oil delivered 7 thereby, and by this means, although all of the-pumps are operated by the same cross head, the stroke of each i one inay be varied independently of the others. These pumps as shown in Fig. l are disposed under the sight 40 feed glasses and thelatter may be provided with id enti fying marks, such as numbers as shown to correspond with similar numbers on or near the pumps, so that the attendant may see at a glance, (mob serving the rate of feed through any glass,'the particular pump to be ad- 4 jnsted if this rate of speed should be changed.

In the construction illustrated each group of sight feed glasses 10 and 11 contains six glasses, the glasses 10 being associated with the six pumps designated 10 while the glasses 11 are designed to cooperate with the 50 pumps 11: However, the system may be reduced or extended simply by varying the number of pumps and sight feed glasses and necessary connections, and

if extended the additional'pumps may be operated by "the cross head 39 as shown in Fig. 1..

From the foregoing it will be understood thatupon the operation oi the pumps l0 and 11" the oil will be drawn from the reservoirs 18 and it), through the headers 22, 23 and from the latter to the sight iced-glasses associatedwith each header, and rise in drops from the nozzles 31 up through the water in the sight feed glasses, thence by the pipes l6 to the pumps, being linally conducted to the parts being luln-icated by the pipes 51. This is the normal operation oi the system. Located at suitable positions on the board 9 are gage glasses 54 to indicate when the supply of oil in each I 20 or 21' while the other end communicates by a pip glasses by wayoi the duct 30: The "27 is reduced, as shown iuFig'. 4,.te i1ermit the fluid to reservoir is nearly exhausted, and in the embodiment of .the invention illustrated these gages are 7 located near the upper corners of the board, the upper end of each being connected by a tube 55 to one of the pipes 56 with one of the headers, as 23. These gages at provided with the usual valves 57 to shut off the oil 1 case of breakage of the glasses or for otherreaso'ns. I

In order to originally charge or to replenish the feed glasses in case the water therein becomes exhaustdii 1 I provide the following mechanism: Mounted on tli l board 9 in a convenient position, as betweenthe series" of sight feed glasses l0 and ll, is an auxiliary pump,-

such as the hand pump 58 shown, which is employed. for the purpose of charging the sight teed glasses with water, but which may alsobe employed for-furnishing additional oil to the parts being lubricated. Extend ing across the front of the board is a tubui or header 59 ,from. which extends aseries of connectipns 60 leading into each sight iced glass. Each coun ction (i0 registers with abduct 61 entering the pas age, 26 of each casing 13, in front of the valve 27 i w en the latter is closed, and which duct is adapted place the con nection 60 in communication wit the sight feed i stem or the valve pass around the same to the duct 30. Each connection 60 is adapted to he closed by a screw valve 62, the stem of which passes through and is in threaded engagement with 3. depending sleeve 63 on the header and has a handle or wheel 64 thereon. v

. The barrel 65 of the auxiliary pump projects through the board 9, as shown in Fig' 3, the plunger 66 of the I same being 'pivotally connected to a lever 67 having 21 depending handle 68 and the upper end of which is pivoted to a link (39 pivotally attached, as at 70, to the board. The pump barrel is provided with a suction valve 7l at its inlet, and a check valve 72 at its outlet,

the said valves being located in a casing 73 connected tothe pump barrel as shown in Fig. 3. Scrowing into the lower end of the casing 73 is a nipple 74, and the valve 71 is seated on and closes the passage through the same, an aperturcd web 75 above the valve serving to I maintain the same in its proper position. Entering I the nipple 74 is a pipe '76 which leads from a suitable source of water supply, such a tank '77 which may be located on the table as shown in Figs. 1 and 2. The pipe 76 is provided with a valve 78 adapted to close the passage through the same. The stem of the valve 78 extends through the board 9 and is provided with 1 hand. wheel 79, asshown. Connecting with the discharge of the pump 58 is a tube 80 which communicates with the header 59.

To originally charge or to replenish the sight feed glasses, the valve in the pipe 76 is opened as are also the valves 62 of the sight iced glasses, the valves 27 being closed. The hand pump is then operated drawing up water from the water tank 77, and forcing the same through the pipe 80 into the header 59. the water finally entering into lhosiglit iced glasses until the 1 latter are tilled. in case certain of the sight [evil glasses are already partially tilled. by means ol' the valve (32 associated with each of said sigh! I'erding I glasses the supply to such sight lei-d glass may be i, "r stopped at any time while the other sight teed glasses "i'il) having their valves still opened are continued to be supplied with water until charged to the desired height.

-By this arrangement of valves, each sight feed glass having a connection with the common header 59, any one may be charged or entirely filled ii the water is partially exhausted without aiiecting the other sight feed glasses. The check valve $2 in the bottom of each sight ieed glass prevents the water therein irom flowing back to the pump or into the reservoirs. As soon itS flle" sight ieed glasses have been charged the valves 62 of all the sight ieed glasses are cltscd and also the valve in the connection 76 leading to the pump, and the valves 27 again opened. The hand -pump also affords means ior iorcing the lubricant contained in either reservoir 18 or 19 to the parts to be lubricated when, for example, the pumps 'lO and 'l l." are out of order or when for other reasons it is not desired to operate these pumps. To this end a common inlet to the pump, such as the tube 81, is provided, and leading to this common inlet tube are connections 82, 83 one oi which communicates with each oi the headers or auxiliary reservoirs 2 2, 23 as shown in Fig. 5. Each oi the connections 82, 83 is provided with a V9,lVQ, 'SllCl1 as the screw valve 84 shownin Fig. 2, he stem oi which passes through a sleeve extending through the-board 9. and is provided with a hand wheel 85 as shown in Fig. 2. The outlet of the pump 58 when/used for forcing oil is the same as that lici'etofore desci'ibcdin connection with the mechanism ior supplying the sight iced glasses with water, to-wit, the tube 80 entering the common header 59. By this an rangement communication may be established, by means oi the valves 84, between the auxiliary pump and either source oi oil supply. For example, assuming that oil is to be drawn irom the rcservoir l8, the valve in the connection 83 is closed while the valve in the connection 82 is opened. The handpump being operated oil is sucked irom the auxiliary reservoir 22 through the conmrction-82 to the common inlet pipe 8| oi the pump and then forced by way oi the pipe 80 into the header 59 up through the sight iced glasses while the valve in the connection 82 is clcscd. When 6'5 another kind oi oil than that usually supplied to any and throughthc pipes Ill through the pumps [0", ll, and to, the parts to be lubricated. As each of the sight icedglasses is provided with a valve 62 for closing theconnection between the header 59 and such sight iced glass, the passage oi oil through any sight. iecd glass may be shut off at will and when oil is being drawn from one source of oil supply the sight'iecd glass associated with tho-othcr source oi oil supply may be closed by means of the valves thereof so that the oil. depending on its character, may beicrced only to the ;,bcarings associated withthe sight iced glasses oi the g-rnam reservoir containing gsucli oil. The operation is the same when oil is drawirirom the reservoir l9, in which case the valve in thec'onnection 83 is openml the oil is bcing delivered ,by the pumps 10", ll alone, both valves 84 are closed. I

liithc case oi a hot bearing, ii it be desired to cocl off with Water, connection may be readily cstablishcd therewith by means of thevaricus valvcs. and

by opening the valve 78 in thowater pipe 7 t) and op crating the hand pump water may be forced to such bearing. Also by means of the construction disclosed,

particular bearing may be iorced to that hearing in the event that this is desired. The main pumps 10 and 1 are designed to be operated with a slow motion so as to iced the oil slowly to the bearings and the hand pump tlicrciore aiioi'ds inhans iOl' sup )lyii-g oil to the hearings in greaterv quantities, as the handle thereoi may be operated rapidly by hand, when it is desired to flush the bearings as, or example, when the niachincry has been out of service ior some time. ll alter charging the sight iced glasscswith water, the hand pump is employed to iced oil to the b( slings, the natcr above the valve 78 will be iorced to the bearings .thcreby clearing the system oi the excess water.

The invention described provides a simple and compact system which under normal conditions is adapted 'to supply oil by means oi an individual pump associated with each sight iced glass and also whereby when these pumps are out of operation oil may be iorccd to the bearings by a pump common to both reservoirs such pump also being so arranged and associated with the other parts as to adapt the same to the charging oi the sight iced glasses with water.

The handles oi the valves 78 and 84 are preicrably grouped close together ncar the center oi the board, as shown in 1, so as'to be readily operated by the attendant, and all oi the valves and other parts, such as the sight iced glasses, gages, and auxiliary pumps are placed within convenient reach of and so as to be readily observed by the attendant.

Mounted on the board in a convenient position, as for example, above the sight iced glasses, as shown in Fig. 1. is a pressure gage 86 having a connection with the discharge oi the-h and pump, as by means oi a tube 87 connecting with the pipe This gage servcs to s indicate the prcssurc on the lubricant so that it may be dctermincd by a glance ii there is any obstruction in or leakage oi the pipes, and also by the fluctuation oi the needle that the oil is iccding.
